Be it known that l, Fniiiiois JnnnoNn, Jr.,

a citizen oi" the United States, residing at Chi cago, in the county of Cook and State of lllinis, have invented certain new and useful Improvements in Draft Appliances and l do' herebydeclare the following to be a full, clear, and exact description ot the invention,'such slilled in the art to sem-e. This invention rela 4es to draft-riggings for y cars, and has for an object to provide a draft appliance embodyingu new and im roved features of reliability, convenience o operation, and economy of construction.

A further object of the invention is to provide a draft-rigging having a barrel arranged to be permanently and rigidly secured to the car structure and with a yoke which may be quickly and conveniently inserted and removed from the bai-rel.

A further obj ect of the invention is to provide in a draft-rigging cushioning-springs and improved means for securing the springs wi thin the device and of engaging the springs operatively.

With these and vother objects in view the invention comprises certain other novel constructions, combinations, and arrangements of arts, as will be hereinafter fully described an claimed.

In the drawings, Figure 1 is a longitudinal vvertical sectional view of the barrel oi thev improved draft-rigging with the spring-carrying yoke removed and the means for at- 3 of the barrel and' yoke shown-in Figs. 1 and *thel draw-head. in transverse section. -is a vertical. sectional view of the cushioning 2. Fig. 4 is a view in end elevation of the yplate-for attachment to the car structure and to which the barrel of the draftrrigging is rigidly secured. Fig. -5 is a view in liront elevationl of the cushioning device secured to tlie'front ol' the car and showing the shalnk of :device and means for ai'ol Tine. taken on line 6 '6 of Fig. 5. Fig. 7 is longitudinal sectional view'o the improved"draftrigging, taken on a horizontal plane slightly below the diametrical middle of the barrel.- i.

views.

The draft-rigging forming the subject-mat ter of' this application may by slight ineditication be applied to cai' structures employing any usiial and ordinary metal iframe g but is here shown and preferably used in associa tion with a. structure employing a single center beam, as shown in the structure forming the subject'inatter of a copending application bearing Serial No. 327,753, 'led July 25, 1906, and in which the central lli-beam is here shown, as at 10, and which extends longitudinally of the car structure and centrally beneath the saine. 'i

The loeain 1G stops short of the opposite ends ot' the car andat its o posits ends is provided .with a bracing mein er (shown as a whole at 11) and comprising a plate-like structure 12, disposed in a plane transversely of the car, and perpendicular' to the longitudinal axis oi the -beam. portion 12 is provided at its bach side or the side away from the end of the car with bracing-webs 13, preferably 'formed as wide at their forward ends as the width oi' the plate structure 12 and with their sides inclined or tapered to the lfbeain l0. The structure 11 is secured rigidly to the l-beam l() in any approved nianner, as by the vrivet 14, extending transversely through the structure and through the I-beam, and by rivets 15, eX- tending vertically through the upper 'and lower portions of the structure 11 and through the flanges of the -bearmso that as The plate-like applied the extremities of the 'l-beain are l 19, rigidly secured to the lower side of the K channel-iron 16 in any approved manner, as by the rivets 20.

Between the head 11 and the channel-iron 16 is rig-idly secured the cylinder oi' barrel 21 of the draftstructure, which is provided at its outer end with a :flange 22, proportioned to conform to the sha ie and site of theplate i2 and rigidly secured-'fthereto in anyapproved IOO IlO

angledrons 17 andlQ andv rigidly secured to the said channel-iron and angle-iroiis, as by the rivets 25.

The' barrel 21 is of any Convenient and approved form and is provided externally with any approved number of ribs 26 for strength# ening the ,barrel structure.' The barrel is .also provided internally with annular ribs27,

'28, 29, and 30, adjacent which supportingshoulders 31,. 32, 33, and\ 34 are formed in vthe. lower wall nf, the barrel, and the said shoulders are respectively provided with depressions or grooves 31', 32', 33', and 34. .he barrel is also provided with ribs 35 and 36, eXtendin radially inward from the wall of the barrel and inposition to hold the springs-37 and 33 `from displacement.

The sprinvs 37 and 38 are disposed within yoke 39 ane rigidly secured at its forward end to theI shank `4() of any ordinary and .usual draw-head and provided at its oppo e site end with a plate 41, secured in any approved inanner, as by oountersunk rivets 42. The yoke is also provided with a centrally- .disposed division-plate 43, secured. in any ap proved manner, as by a rivet 44. Plates 45 and v46 47 and 48 are provided which bear, res eetively, against -annular ribs 27, 23, 29, an 30 and between which are secured the springs 37 and 33 and the usual and ordinary inner springs, yas 49 and 50. For inserting ehe plates 45 ie, 47, and is within the bai-isi,

2l after the yoke 39 is inserted a lurality of openings 5l' and 52 are provided and with similar openings 53, formed Vin the opposite side of the barrel. (Shown in dotted position in Fig. l and in elevation in Fig. 3.)

The yoke 39 with the 'springs y37, 33, 49, ,and in osition is lirst inserted in the opsn- .ing i8, an after being so inserted the plate 45 isdriven through the opening 51 and the plate 46 throughthe opening 53, whereby the springs 37 and 49 are placed under slight tension and the plate 45l in position to rest upon the shoulder 31 andbear against the rib 2-7 'under draft, and the plate 46 to Arest upon the knee 32 and bearfagainst the rib 23 und-er bufi'ng.' Y.The plate 47 is driven, through the opening 52 and the plate 43,.

through the opening 53 to engage opposite ends of the springs 33 and 50 with the plate 47 resting. upon tthe shoulder 33' and bearing against tiie rib 29 under draft, and .the plate 48 resting upon the shoulder 34 and against the rib under builing.

To prevent accidental displacement oi. the lates 45, 46, 47, and 48, openings 54 are orined in the wall of the barrel adjacent the openings ,51", 52, and 53, and through which any convenient securing ineens, as a wire .whiehthey rest.

ring, may be inserted to engage the plates andprevent their returnpassage through the saidv openings.

, For removing the plates when desired a plurality of openings' are vpipvided in the Under side of the barrel structure sind iii position to' register with. the several plates 45, 46,

47, and 43, and through whieh a bolt-or other instrument is inserted for lifting theplatesA out o`i` the groove of the shoulders upon Other openings, as 56, arev also provided registering with the said lates and .throiiglji which any convenient too may be inserted to receive hammer-blows to drive the plates through theA o eniiigsl 51,52, and 53. The extreme annu ar ribs 27 and 30 may' be braced by properly-placed braoingl.ribs 57 and-53 at their opposite sides and with the ribsand 36 bracing them from the inner sides.

To add -to vthe rigidity ofthe barrel relative to the traine of the gear, one. of the ribs 26 is formed at the lower side with an extended lng 59, strengthened in any approved Inanner, as by the web 60, and arranged to be rigidly riveted to an angle or other iron 6l,

which extends from opposite oaiesills or other supporting nieaiis and beneath the barrel of the drait appliance.

The device is further provided with a late 95 62, interposed between the plate -12 o the -oli the said plates by tapering or reducing the said ribs in width, as indicated at 63..

IOO

Vilhile .it .is immaterial troni the .point utility whether the inernber il is formed inf tegral or in halves, it is found more conven ient in the matter of applying andv removing IIO from the center -beain to have the member ii formed inliaives, as indicated more par? tioiilarly in 4. .1

."t will be understood that with the yoke 39 in position within the barrel 2l and with the pilates 45, 46, 47 and 48 properly driven into )osition the tension of draft will be upon the -p ate 4i and dividing-'plate 43Iagainst the movable plates 43 and 46, which are 'iree to inove a limited distaiioe .upon the shoulders 34 and 3l .and against the plates 47 vand 45, bearing rigidly against the ribs 29 and 2'7. in hunting the tension is upon the inner end, of .the shank and upon the dividing-plate 43, bearing, respectively, against the movatle plates and 47 and the springs 37 and 33, bearing against the plates 46 and 43,

which are respectively held rigid `against the being free to move a limited distance upon -the shoulders 31 and 33.

It will be understood that the springs 49 and 50 are held within the springs 37 and 38 by the said springs 37 and 38 surroundingl-and embracing the small springs and that the springs 37 and 38 are held from displacement by the yoke 39 above and below the springs and by the ribs 35 and 36 extending radially from the inner surface of' the barrel to ano engaging the said springs.

For cushioning the draw-head relative to the structure el' the car the device shown in Figs. 5 and 6 is applied to the channel-iron 16 adjacent the opening registering with the barrel member 21,. The cushioning member comprises a casting 63, provided with an opening 64, proportioned to receive and accommodate the shank 4U, carrying the drawhead 55. (Shown in Fig. 6 and broken away.) The casting 63 is provided along 'its upper edge with a Lil-shaped groove, as at 66, to receive and accommodate the joined horizontal flanges of the angle-iron 17 and the channel-iron i6 and is secured upon the said flanges in any approved manner, as by means ol the rivet 67.- The casting 63 is also provided With a flange 68, proportioned and positionedto bear upon the upper innersurface of the lower ilange of the channel-irons 16 and to be secured thereupon, as by the rivet 20.

The casting 63 is further secured in position by ineans of the rivet or bolts 25, by means ot' which the barrel member 21 is secured in position relative to the structural bars v16, 17, and'li).

The casting 62 is provided With an outstanding knee '70, strengthened in any approved manner, as by means of the bracingwebs 7l, and is provided adjacent its upper surface with a sleeve 72. The sleeve 72 is formed tapered and largeriat its outer end than at its inner ond, and therein is disposed a spring 7 3, preferably embracing a small spring 74, which bear at their :ir-.i .er against the inner end ofthe socket formed by the sleeve 72, and at 'their outer ends bear against the inner or rearward surface of the draw-head 65, and are positioned, as by a lug 75, formed upon a plate 75, movable upon said draw-head lt will be noted. that in Fig. l the structure is represented Withoutv the casting 63 being applied thereto, such omission being Vlor the purpose ot showing the barrel member 2l as large as possible, and it is to be understood that the device shown Ain Fig. 6 is a continuation of and an addition tothe parts shown in Fig. 1.

The socket formed by the sleeve 7 2 is tapered larger at its outer end to permit a slight and limited movement of the shank of the draw-head, both laterally and vertically 'in response to the various movements to which the draft-rigging is subject ed.

'UMS

are auxiliary tothe springs 37, 38, 49, and 50 as cushioning-springsor buing and that by 'reason of applying the springs as shown to the external portions ot thecar structure the strain of bul'ling is to a greater extent equalized than when applied entirely Within the lines of the oar structure. While the barrel 2l is shown at Fig. las provided with a bilge, it is to be understood that such bilged form is not essential to the invention, and the term barrel is used as indicating a cylindrical or similar device not limited to a hollow sleeve with a bilge.

What l claim isl.
